The ending...
Did Esposito really leave Gomez to live the rest of his life in that cell? I'm surprised no one really objected to that (yes he was a criminal but even the worst of criminals have rights).
Also, who wanted Esposito dead? I'm sorry, I must have missed it. The movie seems to imply Romano, the guy who was transferred for forcing a confession, but the movie wasn't really clear, and having him killed seems a bit too much for that.
